John Oliver is making the most of having Game of Thrones as the opening act for Last Week Tonight and dedicated his main story to the desert rain frog. If you don’t care about desert rain frogs, it’s only because you haven’t seen them in action. (They squeak like dog toys when they’re mad!) Speaking of being mad, Oliver used a bait-and-switch technique and instead of talking about adorably angry frogs, he turned the subject to something far more serious — lethal injections, which are one of the most common means of executing condemned prisoners.
